Embodiment 1

[0038] In the prior art, the contact parts between the suspension bush and the vehicle body or sub-frame are generally connected by two connection methods. One of the connection methods is planar connection, such as figure 1 As shown, the contact part between the suspension bush and the body or sub-frame is connected by plane 1. When this connection is subjected to a large load, it is very easy to loosen. If you continue to drive under this condition, the fastener will Falling off, causing the suspension to separate from the body, causing a broken shaft accident; another connection method is a serrated surface connection, such as figure 2 As shown, the fastening contact parts of the suspension bushing and the body or sub-frame are connected by serrated surface 2. The serrations in this connection method will damage the contact surface and cause corrosion. After long-term use, the material loss of the rusted part will cause the connection The reduction of the moment of the pa...

Embodiment 2

[0054] This embodiment provides a suspension bushing anti-loosening and anti-broken shaft structure, which includes a suspension bushing, and the suspension bushing is connected with a vehicle body or a sub-frame through fasteners. Preferably, the fasteners are bolts and nuts. Such as image 3 As shown, the suspension bushing includes an inner sleeve 3 and an outer sleeve 4 , and the outer sleeve 4 is sleeved on the outside of the inner sleeve 3 . The materials of the inner sleeve 3 and the outer sleeve 4 have a wide range of sources, such as low carbon steel and alloy steel, and the cost is low.

[0055] Such as Figure 4 and Figure 5 As shown, the inner sleeve 3 has a contact surface 31, the contact surface 31 is in contact with the sub-frame or the vehicle body, and a certain amount of anti-loosening is arranged along the circumference of the contact surface 31 by using an upsetting process. Teeth 5, a certain range of grooves 6 are processed around the anti-loosening ...

Abstract

The invention discloses a loosening preventing and shaft breaking preventing structure of a suspension bush. The structure comprises the suspension bush, wherein the suspension bush is used for beingconnected with a subframe or a vehicle body and comprises an inner sleeve which is provided with a contact surface, the contact surface is in contact with the subframe or the vehicle body, a pluralityof anti-loosening teeth are arranged in the circumferential direction of the contact surface, and grooves are formed in peripheries of the anti-loosening teeth. The suspension bush is tightly connected with the subframe or the vehicle body, so that the problems of looseness and shaft breakage of the suspension bush commonly existing in the prior art can be effectively solved, the operation stability of a chassis is prevented from being reduced, the driving quality is improved, looseness of a vehicle after a certain service life is avoided, and potential after-sale complaints and recall risksare eliminated.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a suspension bushing anti-loosening and anti-broken shaft structure. Background technique [0002] The suspension positioning parameters of the vehicle under various actual operating conditions will change dynamically, which greatly affects the vehicle's handling stability and ride comfort. In order to solve the above problems, the existing automobile suspension system generally adopts a bushing structure. On the one hand, the bushing structure can avoid the mutual movement interference of the suspension components caused by the rigid connection, and on the other hand, it can attenuate and buffer the The impact and vibration of the ground achieve a balance between handling stability and ride comfort. [0003] Suspension bushings are the joints that connect the body and suspension, and the suspension control rods can be connected with the body or subframe by using the suspensi...
